Exposure also depends on your ISO setting in RAW unless you shoot everything at base ISO and then push in post.

Could you clarify this statement? How does exposure depend on your ISO setting when shooting raw in manual mode (as dpreviewreader wrote, and as I shoot 95% of the time)?

You do have to choose an ISO (or let the camera choose it for you) even when you use RAW mode, yes? It doesn't just magically take care of itself. The ISO setting determines, to an extent, the range of apertures and shutter speeds you can use. Which in turn determines your exposure. Photo 101.
